What does 'car coal mining' mean?
2 Answers
Car coal mining refers to cleaning carbon deposits. 'Coal mining' is actually a shorthand term for disassembling and cleaning the engine's intake system. During vehicle operation, as long as the engine is running, carbon deposits will form. When these deposits accumulate excessively, they can affect the engine's normal operation. Therefore, it is necessary to clean these carbon deposits regularly based on the vehicle's usage. Below are some methods for cleaning carbon deposits: In various 'auto parts markets' and 4S shops, due to technical reasons or other factors, the common method used for cleaning carbon deposits is 'intravenous injection.' However, this only addresses the symptoms, not the root cause, and is particularly ineffective for slightly older vehicles. Simply put, the reason is that these carbon deposits are too 'stubborn.'
Back when I was first learning to drive, I was completely baffled when I heard people talk about 'car coal mining,' thinking it meant putting coal in the car. Actually, it refers to the process of cleaning carbon deposits from the engine, especially from driving in stop-and-go city traffic where incomplete fuel combustion leaves carbon residue on the pistons and valves. If not cleaned, the engine loses power, fuel consumption spikes, and in severe cases, it can cause engine shaking or starting difficulties. I think this is super important. Regularly adding fuel additives can help prevent it. Don’t underestimate carbon buildup—it can cost you thousands in repairs. Especially with my old car, during a recent service, we found excessive carbon buildup. When we opened it up, everything was black and dirty. After cleaning, the car ran smoothly again, just like new. I recommend checking every 10,000 kilometers—don’t wait until problems arise to regret it.
